resolving implicit type issues when including this header.

riscv: kernel: support booting non-contiguous non-zero-based hart IDs
Currently, OP-TEE assumes 0 <= hartid < CFG_TEE_CORE_NB_CORE,
and must be contiguous, which fails to accommodate different
CPU topologies. For example, some RISC-V platforms, such as
the HiFive Unmatched board, do not run Linux and OP-TEE on
hart0, as it is a monitor core without supervisor mode support.
To address this, introduce hart_index, which is used to index
per-hart structures, such as thread_core_local and root_pgt.
The hart_index will range from 0 to (CFG_TEE_CORE_NB_CORE - 1),
and the primary hart will have an index of 0.
Additionally, a new function, boot_primary_init_core_ids(),
is added to initialize secondary hart IDs for booting via
sbi_hsm_hart_start().
